Patentappiication ser. No.6s,525, led March 12, 1936, I have described adevice for fixing window,` glasses, panels, and nat pieces of.

the same kind in a frame or support schas the recess of a window. 'I'hexation device includes August 3, 1931, 'serial No.`15'z,zo9 innameAugust 8,1936 l toiaims. .lomo-56.4)

Figs. 3 and 4 are a transverse direction with respect to the panel, f

said retainer having its rear portion rigid with the frame'or supportand a freely exible front portion provided withl a beaded edge adaptedto retain the panel in contact with the backing 'means;,in an embodimentof the said devicethe edges ofthe panel are inserted in `anelasticsheath which is positioned between afprojection or ange on therabbet orlike part ofthe frame' or support, and a locking frame held inplace by the panel retainer.

The object of the present invention is to provide changes andimprovements in a device of this kind, especially with a view tofacilitating two other embodiments of the invention, respectively; Y

Figs. 5 and-,6 are sectional views, also analogous to Fig.' -1, butvcorresponding to embodiments of the invention in which the retainersare wholly independent. l

- In the diilerent figures of the appended drawing equivalent elements.are designated by the same reference characters, respectively.

'I'he glass pane I' has its edges inserted in a marginal sheath orcasing 2 of resilient material,

rubber for instance,Y of U-shaped section, posi-- tioned in a housingprovided in therecess 3 of the window. 4This sheath or case 2 is heldbeftween a wall of the housing and alocking or aux-l iliary 'frame 1 ofL-shapedl section. At spaced apart points, on the periphery on' theouter side,

frame 1 has projections or lugs I of rectangular section, which areformed to protrudeby a pres' determined amount on the auxiliary orlocking removal of the panel or similar part from the` frame or support.

- According to an essential feature of the present invention, theretainer is attached to the locking or auxiliary frame, or even iswholly independ ent thereon, instead of being attached to the support orframe. When the retainer is made as a wholly independent element, itisresiiiently dis- A torted in order to be snapped into position and it ismaintained in final position by reason of its own resiliency.

frame. Lugs -1 are planed on their outerv faces vthrough which .they arein contact with the wall l ofthe chousing of the window recess which isat right angles to the wall against which sheath 2 is directly applied.l

Furthermore, accordingto another feature of the vpresent invention, Iprovide notches or recesses in the elements of the device so as toenable introducing a tool for bending or disengaging the retainer andthis facilitating withdrawal of the locking or auxiliary frame. Y

Other features. of the present invention will resultfrom the followingdetailed description of some specific embodiments thereof.v

Preferred' embodiments of, the present invention will be hereinafterdescribed, with reference to the accompanying drawing, given merely byway of example, and in whichr' 1113.51 is a sectional view 'of a glasspane po`rtioniixed in a window frame by means of a de- On the side ofthe frame that carries the lugs 1' there are fixed, for instance bymeans of rivets. elastic tongues 5, constitutingthe pane retainers.

The hook-shaped freeend 6' of the Vtongues en gages a groove la providedin wall 4 as shown.

In view of the shape above described, the supporting lugs 1' hold theframe in an accurate po'- sition inthe window recess and, owing to theprovision of such lugs, the iinal trimming or nishing of the lockingframe is expeditive since only a small number of.narrow surfaces, vizthe bear- A ing surfaces of the lugs, has to be machined.

Rivets or like fastening means for attaching the retainer to the lockingiframeA are preferably vice made according to au embodiment of thepresent invention, this section being made in a plane at right angles'to the general plane .of the glass pane, on the line I-I of Fig. 2

Fig.'2 is a sectional view at right angles to the view of Fig. 1 andmade along the broken line positioned where the lugs project from saidframe as shown. By reason of the clearances between lugs 1?. atool suchas a screw-driver maybe inserted between the retainer 5 and the wall 4,for

bending the retainer toward the Jframe and dis-v engaging, its hook fromgroove la, whereupon the auxiliary frame can be removed from the windowrecess.

In the embodiment Iof viding a recess la in the bottom of thev housing,

I-provide relatively wide cavities or notches 4b in the front part ofsaid housing, near the 'outer side of the window recess, and I dispose'the retainers 5 in an inverse position as compared with that rig.' 3,,instead vor pm they occupy in the embodiment of Fig. l, each oi saidretainers bearing against a shoulder Ic provided on the edge of thecorresponding notch. With this arrangement, it is easy to vinsert ahook-shaped tool behind the retainer so as to disengage it by pulling inthe direction of arrow C.

I may also provide in the window structure inclined holes II which openbehind the tongues and enable of pushing said tongues from behind. inthe direction of arrow D, by means of any suitable tool or rod. fcourse, in this case, the

above mentioned notches are unnecessary.

On Fig. 4, I have shown another embodimentof the elastic retainer; theretainer is longer and is folded back at 5a' then bent into a hookededge adapted for engagementv with a lip 0r abutment 4c projecting on theouter margin oi' groove lb; in the example shown on Fig. 4, the lockingframe I has a relatively less thickness, as compared to the depth of thewindow recess, than in the instance of Fig. 3. For removing the glasspane. it suilices to lift the retainer by means of any flat toolwhich'isintroduced into the folded portion 5a of the retainer, so as todisengage its hooked edge from the-abutment 4c.

Figs. 5 and-6 show embodiments of the invention in which the retainersare no longer ilxed to the window recess or the frame but are whollyindependent and are held in position merely by .their own elasticitywhich, so `to speak, keeps them caught as a consequence of their shape.

In the embodiment of Fig. 5, the rear edge of the retainer is bent 'andforms a hook which engages a groove I2 provided in the bottom part ofthe housing of the window recess behind a heel or rib I3 -provided `inthe lateral wall 4 of the window recess. The retainer, which is slightlycurved or bent, bears at two points, on the one hand on heel I3, andlonthe other hand near the outer edge-of wall 4. The front edge of saidretainer' is folded back at 'Ib over the body of said retainerdtself andthe end. of this folded portion is slightly bent ,upwardly So as to comein front of lthe front face of the auxiliary or locking frame I and tohold itin position while compressing sheath l2 against the bottom of thehousing of the window recess. The retainer is thus-kept applied againstheel I3 by the frame 'I itself. For removing-the pane, it is onlynecessary to depress the retainer at I4 in the direction of arrow E soasV to clear the auxiliary frame l from the holding edge of theretainer, wherestationaryrear'abutment for said pane, substantiallyparallel with the plane of the pane, having a front projection deiiningaback groove between the rear flange and said projection; a removablefront abutment for said pane, also substantially parallel with 'theplane of the pane; and a resilient retainer substantially comprisingthree integral portions, a front portion attached' to the movable frontabutment, a but slightly f bowed intermediate portion positioned in aplane substantially at right angles to the plane of the pane and a rearportion in the form of a hookA removably engaging said groove, theretainer being adapted in operation to be stressed to tension betweenthe front abutment and the groove. 2.
